Variable-focus liquid lens by changing aperture
, 2005 We propose an adaptive liquid-filled lens, which consists of an elastic membrane, a solid plate, and an annular sealing ring; a liquid with a fixed volume stored in lens chamber. The key part is the annular sealing ring which looks like an iris diaphragm.

Ultrathin Tunable Lens Based on Boundary Tension Effect
Sensors, 2019 Solid and liquid lenses are commonly used in optical design. Such lenses have suitable thicknesses due to their working principle and processing mode. Thus, zoom optical systems comprising solid and liquid lenses are extremely large. This work presents a

Advanced Functional Materials, EarlyView.We introduce a capillary‐filtering‐based particle‐filling (CFPF) process that simultaneously forms vertical thermal pathways and electrical vias within µ‐pores. In situ microfluidic analysis reveals that capillary‐driven velocity gradients generate vorticity that governs µ‐platelet rotation and vertical alignment.

Reduced Graphene Oxide Transparent Electrodes Enabling Compact Soft Tunable Lenses
Advanced Functional Materials, EarlyView.By spray‐coating an elastomeric membrane with reduced graphene oxide (rGO) at various surface densities, elastomeric actuators are manufactured. Electro‐mechano‐optical characterizations show the suitability of rGO as an effective material for compliant, semi‐transparent electrodes, enabling soft electrically tunable lenses with a compact form factor ...

Voltage induced spreading and liquid optical devices
, 2013 An experimental investigation has been carried out into Liquid dielectrophoresis (LDEP), in which dielectric forces are used to actuate bulk liquid spreading and to imprint a deformation pattern at a liquid air surface.

Aberrations of liquid crystal lens
Electronics Letters, 2006 Wave-front aberrations of a liquid crystal variable-focus lens driven by two voltages are evaluated. An appropriate operating voltage ensuring the smallest RMS aberration is first determined. It is kept unchanged and the lens focus is tuned by a controlling voltage.

Nonmechanical three-dimensional beam steering using liquid lens and liquid prism
, 2020 In this paper, we present a nonmechanical three-dimensional beam steering system using electrowetting based liquid lens and liquid prism. The optical design for the radius of curvature of the liquid lens and the tilting angle of the liquid prism was ...
